From 7302f0d6f939247c1c658b79aba0866c92560ff7 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Subject: [PATCH] drm/vc4: dsi: Add support for DSI0
Commit 4b265fe11fad4234b12d92dd8091f9aa0c878eea upstream.
DSI0 was partially supported, but didn't register with the main
driver, and the code was inconsistent as to whether it checked
port == 0 or port == 1.
Add compatible string and other support to make it consistent.
